T/CECA 26-2019 The reliability test method for piezoelectric ceramic electroacoustic elements
Basic Information
Scope
Main technical content: This standard specifies the general requirements, test methods and procedures, test records, pass/fail criteria, and reporting requirements for reliability tests such as high-temperature storage, high-temperature operation, low-temperature storage, low-temperature operation, temperature cycling, constant humidity and heat, vibration, collision, impact, free fall, high-temperature lifetime, solderability, resistance to soldering heat, high-temperature resistance, high-voltage resistance, and failure rate of piezoelectric ceramic electroacoustic components. This standard applies to reliability tests required in the development, production, use, and third-party inspection of piezoelectric ceramic electroacoustic components.
